Why slow compression with conducting walls should be isothermal?
I know that for an isothermal process heat transfer is necessary so process should be slow and walls should be conducting for heat transfer to occur as a process cannot be isothermal and adiabatic at ...

Temperature increase in fixed volume due to gas injection
I have a vessel of fixed volume with adiabatic boundary which is initially filled with air at pressure of 1 atm and temperature of 300 K. Now, I inject air from an external source at a fixed flow rate ...

In an adiabatic process, if there is no heat flow between system and surroundings, then why don't we consider temperature to be constant always?
How can the temperature of a body change unless heat flows in or out of it?
So shouldn't all adiabatic process be considered isothermal too? but that is not true as both the processes have different ...

How does speed of a thermodynamic process determine its type(adiabatic or isothermal)?
The part explaining adiabatic process in this answer says that,
In reality, adiabatic processes are approximations. They work best with systems that are almost isolated, but have a limited way of ...

Why is the final temperature of irreversible adiabatic processes higher than that of reversible adiabatic processes?
Suppose an irreversible adiabatic expansion process and a reversible adiabatic expansion process are starting from the same initial state, say, P1V1. Now, let both of these processes have equal ...

Question regarding using $dU=nC_vdT$
In an Adiabatic process ,$Q=0$ (heat added or removed from the system is 0).
First law of thermodynamics states that ,
$dU=Q-W$...(1)
$Q=0$ .
Therefore $dU=-W$.
Now my question is why $dU=nC_vdT$ used ...

How to derive $ TV^{1-\gamma}$? I get $ \frac{T}{V^{1-\gamma}}$ [closed]
For an adiabatic process we have $dQ=0$, thus the first law gives:
\begin{align}
\mathrm{d}E &= \mathrm{d}W, \\
nC_V \mathrm{d}T &= - P\mathrm{d}V = - \frac{nRT}{V} \mathrm{d}V, \\
\frac{\...

Radial dependence of temperature for adiabatic expansion of ideal gas
If the solar wind propagates out adiabatically with a constant speed and
can be regarded as an ideal gas, how the solar wind temperature depend
on radial distance from the sun $r$, i.e. $T$ as a ...

Can adiabatic heat exchange between different temperatures ever be reversible?
I've been told, A volume 2X of Temperature 0.5*(T1+T2) is always at higher entropy than thermally insulated volumes, 'X' at T1, 'X' at T2 put together.
Let's take Sys1 (A volume 2X of Temperature 0.5*(...

Why is $c_p/c_v$ term introduced in adiabatic process?
In an adiabatic process we know there is no change in enthalpy or basically enthalpy change is zero. which means any external work done the internal energy does equal opposite work so as to keep $dH=0$...

Does an isothermal process always imply an adiabatic process?
In an isothermal process, temperature of a body remains constant.
In an adiabatic process, the net heat transfer entering into a body is zero.
Since no change in temperature implies than no heat has ...

Reaching Absolute Zero by Adiabatic Expansion
We know that an adiabatic expansion of a P-V system leads to reduction of temperature. Can this method be employed to continually reduce the temperature until we have exhausted the systems complete ...

Cooling due to adiabatic expansion
Consider an ideal gas inside a cylinder-piston setting. Now, we know that the temperature of the system reduces under adiabatic expansion.
For an ideal gas we know that the molecules move about ...

Intuition on Kinetic Theory - Does temperature change during an adiabatic expansion?
I was reading the chapter "The Kinetic Theory of Gases " from the Feynman Lectures on Physics, where Feynman gives the intuition for why temperature is defined the way it is and what happens ...
